Editing DataCite DOI (section)

==External DOIs==
If an eprint already has a DOI associated with it, e.g. one that has previously been provided by a journal publication, then this will be listed as the '''Current DOI'''. The DataCite DOI Manager screen will indicate where this DOI redirects to, and will still present options for an '''Available DOI''' if the DOI for this record can still be minted on DataCite.

The '''DataCite DOI Manager''' will also run a search of the eprint’s title against DataCites findable records, to see if a DOI has been coined previously. If one of the records matches the eprint, the '''Claim DOI''' button will set the eprint’s DOI metadata field to the DOI already on DataCite.
